Abstract
In connection with stochastic resonance (SR), we study the dynamics of a particle in the asymmetric deformable potential (ASDP) and double well deformable potential (DWDP). The phenomenon of SR is known to occur in sinusoidal and some nonsinusoidal systems. However, the question of the occurrence of SR in the ASDP and DWDP systems has not been resolved. This numerical work presents the characterization of stochastic resonance in terms of hysteresis loop area (HLA) in both the models. The average input energy displays a double SR peak as a function of temperature in the ASDP model and one peak of SR which occurs at weak temperature in the DWDP model. The presence of Chaos is also investigated in DWDP system where we show that the Chaos can destroy the SR phenomenon.
